SECTIONAL FEED ROLL FOR PLANING MACHINES.

Application filed January The present invention relates to sectional feed rolls for wood planing machines and has for its object to provide an improved construction of this character.

In the accompanying drawings:

Figure 1 is an elevation, broken away, of a feed roll mechanism embodying a preferred form of my invention, and

Figure 2 is a section on the line 11-11 of Figure 1.

Referring to the illustrated embodiment of my invention, 2 are spaced bearingmembers in which is journalled a shaft 3. Mounted on this shaft is a plurality of cylindrical sections at each having a toothed periphery and a bore 5 substantially greater in diameter than the diameter of the shaft whereby the sections are adapted to move independently transversely of the shaft. Each section has a recess 6 communicating with its bore in which engages a tongue 7. This tongue is mounted in a channel in the shaft 3 and by reason of its engagement in the recesses 6 of the sections the transverse movements of the latter are guided and the sections are caused to revolve with the shaft.

The shaft has collars 8 secured thereto in engagement with the outer ends of the hearing members 2. Collars 9 are mounted on the shaft in engagement with the two end sections of the feed roll and nuts 10 are mounted on the threaded portions of the shaft in engagement with the collars 9. By properly adjusting these nuts the cylindrical sections of the feed roll are adapted to be held in snug engagement with each other without any binding action.

A guide bar 11 extends above the feed roll and is secured at its ends to the bearing members 2 by screws 12. This guide bar has an inverted channel 13 therein and a plurality of plungers 14, corresponding in number to the cylindrical sections of the said roll, are fitted in this channel, to move vertically therein. Each plunger has a bifurcated lower end 15 carrying a pin 16 upon which is journalled a toothed wheel 17 Each toothed wheel has a wood bushing 18. Each plunger has a bore 19 therein opening at its upper end and a spring and are adapted I 22, 1925. Serial No. 4,020.

20 is arranged in such bore. The upper end of each spring is engaged by a follower 21 which is engaged by a set screw 22 carried by the guide bar and held in adjusted posit1on by lock nut 23. It will be apparent that the springs 20 press the toothed wheels 17 into engagement with the cylindrical sections 4: but permit the cylindrical sections to rise and fall independently of each other.

While I have shown and described a preferred embodiment of my invention it will be understood that changes may be made in the details of construction without departing from the spirit of the invention or scope of the appended claims.

I claim: 1

1. A sectional feed roll mechanism, comprising spaced bearings, a shaft journalled in said bearings. a plurality of cylindrical sections mounted on said shaft between said bearings and each having a toothed periphcry and a bore substantially greater in diameter than the diameter of the shaft, whereby the sections are adapted to move independently transversely of the shaft,a connection between the shaft and each sectiop for guiding the transverse movements of the latter and for causing the sections to rotate with the shaft, a toothed wheel arranged above eachsection and meshing therewith, and yielding means pressing said toothed wheel into engagement with its section, substantially as described.

2. Asectional feed roll mechanism, comprising spaced bearing members, a shaft journalled in said members, a plurality of cylindrical sections mounted on said shaft between said members and each having a toothed periphery and a bore substantially greater in diameter than the diameter of the shaft, whereby the sections are adapted to move independently transversely of the shaft, a connection between the shaft and each section for guiding the transverse movements of the latter and for causing the sections to rotate with the shaft, a guide bar extending above said sections and connected at its ends to said bearing members, said guide bar having an inverted channel therein, a plunger slidably fitted in said channel 5 ing a bore therein opening at its upper end above each section for Vertical movements therein, a toothed Wheel journalled in the lower end of each plunger and meshing With the corresponding section, each plunger hav- 7 7 a spring mounted in the bore of each plunger, a follower in engagement With the upper end of each spring, and a set screw carried by said guide bar and engaging each follower, substantially as described. 10

In testin'ionv whereof I have hereunto set my hand.
